Polyethylene (PE for short) is a thermoplastic resin made by polymerization of ethylene. Polyethylene is a polymer formed by the polymerization of ethylene. The product has been developed for about 60 years. The global polyethylene production ranks first among the five general-purpose resins. The molecule of polyethylene is a long-chain linear structure or branch structure, which is a typical crystalline polymer. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the minimum use temperature can reach -100~-70°C), has good chemical stability, and can withstand most acids and alkalis (not resistant to acid with oxidability). It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation.
The mineral 400ml plastic bottle for drinking water that we must use in our lives is a polyethylene bottle made of polyethylene (PE). Because PE is chemically stable, resistant to acid and alkali corrosion, is insoluble in general solvents, and does not absorb water, and it has excellent insulation. It is often used to make mineral water bottles, decorative plastic pump bottles, body wash bottles, etc.
Advantages of polyethylene bottle:
1. Polyethylene bottles have excellent low temperature resistance (the lowest temperature can reach -70～-100℃), good chemical stability, can withstand most acids and alkalis (not resistant to acids with oxidizing properties), and are insoluble at room temperature. Compared with general solvents, it has low water absorption and excellent electrical insulation.
2. The material of the polyethylene bottle is relatively light, resistant to pressure, not easy to break, and has a particularly good seal. It is not only moisture-proof, but also particularly hygienic, and fully meets the special requirements of pharmaceutical packaging.
3.This is a kind of bottle that can be directly used for medicine packaging without washing or drying. It belongs to a type of packaging material and is suitable for tablets, capsules, granules and other medicines. #400ml #plastic #bottle
